What you will do

We are seeking a Senior Mechanical Commissioning Engineer to own and lead the commissioning strategy for liquid‑cooled mechanical systems within next‑generation data centre deployments. This role sits within a central commissioning function, responsible for developing commissioning methodology, authoring procedures, and ensuring consistent, high‑quality execution across regional site teams.

The successful candidate will be a recognised technical authority in liquid cooling and mission‑critical mechanical systems, with the credibility and experience to govern commissioning activity from design review through IST, client demonstration, and handover.

How you will do it

Define commissioning philosophy, test levels (L1–L5), hold points, and acceptance criteria
Provide design-for-commissioning input during early design and product development phases
Act as final technical authority for mechanical commissioning issues and risk resolution

Systems Scope

Direct‑to‑Chip (DTC) liquid cooling systems
Coolant Distribution Units (CDUs)
Facility and secondary heat rejection systems (dry coolers, chillers, plate heat exchangers)
Pumps, valves, pipework, filtration, water treatment
Leak detection and containment systems
Integration with IT thermal loads and controls

Procedure & Documentation Development

Author and maintain:
- Mechanical commissioning plans

- Define measurable pass/fail criteria for all mechanical systems

Site & Regional Team Oversight

Provide governance and technical oversight to regional mechanical commissioning teams
Audit commissioning execution for compliance with strategy and standards
Witness Factory Acceptance Tests (FAT), Site Acceptance Tests (SAT), and critical onsite tests
Support regional teams with complex fault finding and system tuning

Integrated Testing & Handover

Collaborate with electrical and controls leads during:
- Integrated Systems Testing (IST)
- Failure‑mode and redundancy testing
Support client demonstrations and formal handover
Ensure readiness for live IT load introduction

What we look for

10+ years’ experience in mechanical commissioning of mission‑critical facilities
Demonstrable experience commissioning liquid‑cooled data centre systems.
Strong working knowledge of:
- Hydronic system design and commissioning
- Controls and BMS / PLC interaction
- Redundancy and failure‑mode analysis
Experience working across multiple geographies with regional teams
Relevant engineering qualification (Mechanical Engineering or equivalent)
Calm and authoritative under pressure
Strong technical documentation skills
Pragmatic, outcome‑focused approach to commissioning
Willingness to travel to support FATs and critical site activities
Able to challenge unsafe or non‑compliant commissioning practices
